"Digestive tract" of a tapweorm
Although Tapeworms are thought to be a very complicated animal to understand, it is very simple. Being in the phylum Platyhelminthes, it is an exception to the normal digestive system. Tapeworms don't have a system where nutrients are broken down and then released from the body. Rather then having to break everything down by itself, it relies on the host animal in which it lives inside of to digest the food it will eat. This parasitic animal takes in the food/ nutrients it needs from the host animal and then stores it in its proglottids. These nutrients are used by these proglottids to live and reproduce.
